Hi, I'll be going to Australia in a few weeks and I was looking at how to get around 500MB - 1GB of data over 12 days. I'll be staying in Surfer's Paradise, Cairns and Sydney. I was looking at the $20 data pack from Telstra: http://www.telstra.com.au/mobile-phones/prepaid-mobiles/extras/index.htm Is this a sensible idea? Can you have JUST the data pack without a pre-paid offer? These things are a bit of a mystery to me Otherwise I was thinking about the $2 days from Optus, but I don't know about their coverage where I'm going. (Someone on here said that Telstra's coverage is great.) Really, any help is welcome. Thanks!
